Finding the Perfect Ring Size

Choosing an engagement ring is an exciting experience. If you decide to choose a ring together, be sure to get a measurement two or three times, and at different times of day, to ensure you get the right size. The ring should fit comfortably, but not slip over the knuckle without help.

If you want to make this proposal a complete surprise, you'll need to get her ring size in secret. Here are a few ways to get an accurate ring size without her knowledge:

Take one of her rings to a jeweler to be sized.

Ask her mother if she knows her ring size.

To be absolutely certain, ask one of her trusted friends to create a situation where they could get her ring size. If she suspects, it will just be part of the fun.

To order a 1/4 ring size, please call Ritani Customer Service at 1.888.9RITANI (1.888.974.8264)

Channel-set

Set and sealed inside a fine metal channel. Only the edges are concealed for security and maximum sparkle . This setting allows for the diamonds to be set so close together they create a continuous stream of brilliance. A channel setting also provides the most safety for your diamonds, with metal edges to protect them from bangs and scrapes.
